The record card reading machine carried by an escapement bar IS. The escape- -ment bar has bottom teeth meshing with a gear I6 driven by the usual spring motor drum I! in the proper direction to urge the escapement bar toward the left, but its movement is controlled by escapement dogs 41 and 48 which can be brought into engagement alternately by escapement operating means described in said application Serial No. 450,248, to allow a step-by-step movement. Below the card is a row of sensing brushes I2 mounted upon an insulating bar 90,

which is normally dropped to disengage the brushes from the card, but which can be elevated by a parallel bar mechanism 93 operated by the. armature 94 of an electromagnet 92. As it swings to operated position, the armature 94 opens a pair of contacts 95, to be referred to later. Above the card is a contact roller 9| with which any brush finding a perforation in the related index point position of the card comes in contact.

In addition to the detail card sensing mechanism, the machine has a master card sensin mechanism, which is adapted to sense the columns of a master card concurrently with the sensing of the columns of the detail card. The mechanism is similar in construction to the on shown in the patent to Shafer 2,315,741. The details of the construction of this mechanism can be learned from Figs. 1 and 9 of said patent. It comprises a bed (not shown) adapted to support a master card MC similar in shape and size to the detail card. The master card is placed between two fingers 91 and 98 fixedly mounted on the escapement bar I5. Below the master card is a row of sensing brushes I0| mounted upon an insulating bar I02 which is normally dropped so that the brushes are out of contact with the card, but which can be swung by its parallel bar frame I03 operated by the armature 14a of a magnet I04 to raise the brushes into contact with the bottom of the master card. Above the latter is a sensing roller I05 with which any brush finding a hole in the master card makes contact.

The machine is also provided with mechanism to cause the card feed to skip over certain fields. This mechanism (see Patent 2,315,741, Fig. 7) comprises a skip lifter 5| inserted under the do 41 and resting at its inner extremity upon the upper edge of an exchangeable skip bar 58. The skip lifter can be shifted to the rear by a pivoted arm 54 operated by a skip magnet 56 and has near its rear end an inclined bottom edge, which rides up on skip bar 50 and lifts the dog 41 free from the escapement bar l5. The skip bar 50 may have a high surface 501:. capable of lifting the dog 41 when the skip lifter is in forward position, a medium surface 50b capable of lifting.

' tape 200.

construction will not be described here, but some of them will be referred to later in connection with the circuit diagram.

Tape perforator The card sensing machine controls a tape perforator. The construction of this machine is fully disclosed in the above mentioned Mills &

Rabenda application Serial No. 450.248 and is shown in semi-diagrammatic form in Fig. 2 of ,thepresent application. It comprises individual punch elements 2l0, one for each of the five units of the telegraphic code and one for punching the feed hole 202. There is a die block 2 for the Dunch'elements and individual springs 2l3 normally hold the latter retracted. Each punch element has a recess 2 I 6 into which is inserted one end of a rockable punch lever 2|! having an oval shaped opening 2l8. An individual punch lever is provided for each punch element. An elongated cam or eccentric M9 on a'shaft 220 is disposed within the oval shaped openings of the punch levers, to support and actuate said levers. Normally, during the rotation of the eccentric, the punch levers move downward and upward about their pivotal connections with the punch elements 2lll. Under these conditions the free right ends of the punch levers are rocked idly downward and upward.

A plurality of latch members 221, one for each punch lever, are pivotally supported'by a shaft 228, in cooperative relation to their respective punch levers. The downwardly extending arms 221A of the latches have latching shoulders 230 to engage under the right ends of their punch levers 2l1. All of the latches, except the one pertaining to the feed hole punch, have arms 221D extending to the right and three of them, in alternate positions, also have leftwardly extending arms 2213. The latter arms are biased upward by individual springs 234, while the arms ZnD of the other three latches are biased downward by springs234 anchored to a stationary pin 236. The springs 234 urge the latches in clockwise direction but, with the exception of the latch pertaining to the feed hole punch, the latches are normally held in retracted position, with the hooks 230 out of the path of the punch levers, by their rightwardly extending arms 221D, the ends of which are detained in recesses 233 of related armatures 23l pertaining to tape punch selector magnets 232, only two of which are shown in the drawings. Upon energization of the individual magnets 232, the related armatures 23! are attracted and release their respective latches,permitting them to swing under the influence of springs 234,,to engage their shoulders 23v under the free ends of the corresponding punch levers The shaft 220 is operated in a start-stop manner, by means to be described presently, the latch levers 221 which are to be engaged being released at the start of each cycle, when the right ends of the punch levers are in their uppermost positions, or approaching their uppermost positions. Thus, upon latching of a punch lev er. 2 l the following rotation of thdeccentric'z'ls rocks-the punch lever counterclockwise about its pivotal connection with the latch lever forcing the related punch element 2H] through the telegraphic A restoring bail (not shown) is provided to'restore the latch levers 221 at the end of each punch cycle and a locking ball 23! may also be provided to lock the latch levers in effective or ineflective position through the punch cycle.

Means are provided for intermittently advancing the tape 200 near the end of each cycle of rotation of the shaft 220. The tape is fed from a supply reel (not shown) through a tape feeler mechanism such as shown in the above mentioned copending application. The feeler mechanism operates the tape contacts 3|! shown on p the circuit diagram (Fig. 12a) to indicate exhaustion of the tape supply. The tape is fed between the die block 2 and the punch elements 2") and over a sprocket wheel 26l. The sprocket wheel 26l has a series of teeth 264 to engage the feed holes 202. The feed holes are punched by a punch element 2 ID, the punch lever 2 l 1 of which is constantly latched by a stationary latch lever 221 having no latching arm 221D, so that a feed hole is punched on each revolution of the shaft 220. The shaft 261 of the sprocket wheel 26| has secured thereto a ratchet wheel 268, which is advanced step by step by a, pawl 269 pivotally mounted on a cam follower'arm 210. A spring 212 anchored to a fixed part and hooked into the pawl 269 urges the pawl against the ratchet 268 and pulls the-arm 210 to the right so that a roller 210a. thereon bears against a cam 2H on shaft 220. Near the end of each cycle of shaft 220 the high point of cam 2' moves the cam follower arm 210 and pawl 269 to the left to advance the ratchet wheel 268 and the sprocket wheel 26! one step. Thus, the tape 260 is fed to present the next position thereon to the punch elements. cam 2'" passes, the pawl 269 is retracted to engage the next tooth of the ratchet wheel 268.

The start-stop operations of the shaft 220 are controlled by a one revolution clutch 290, which is shown only in outline in Fig. 11, but may be constructed in the manner fully disclosed in United States Patent 2,206,646, issued to Schneider on July 2, 1940. The clutch is controlled by "a dog lift lever 293, which when stopped by a. detent 294 disconnects the shaft 220 from a constantly driven shaft 298 driven by motor 3M through a worm and wheel gearing 302. The detent 294 also determines the stationary angular position of the shaft 220. Detent 294 is part of a rocker arm 295 pivoted at 294a and biased counterclockwise by a spring 296. The arm 295 has a bent over portion 299 which acts as an armature to a clutch magnet 399. When the magnet is energized, the detent 294 is retracted from the dog lift lever 293 and the clutch engages. The shaft 220 is rotated until the magnet 380 is deenergized, dropping the detent 294 into the path of do lift lever 293, The engagement of the detent with the dog lift lever disengages the clutch and stops shaft 220 in a fixed angular position.

A pair of normally open bail contacts 3 are operated by a pivoted bail lever 3I5, which is rocked by the upwardly extending arm 221a of any released latch lever 221, to close the contacts 3. The contacts 3 are employed, at certain times, for controlling the energizations of the clutch magnet 360.

Two additional pairs of contacts Cl and C2 are operated cyclically by related cams 399 secured to shaft 220. The functions of these cam controlled contacts will be explained later. They are timed so that the contacts Cl close before the end of a punch cycle and remain closed when the punch shaft is stopped and during the first part of the next cycle, while the connumber of the depot or branch ofiice.

When the high part of the tacts C2 are normally open, close after the cycle begins, and remain closed during the first part of the cycle (see timing diagram Fig. 10 in application Serial No. 450,248).

The telegraphic code perforated in the tape is shown in Fig. 9. Each code combination representing a letter may have a second significanceit may represent a numerical digit, a punctuation mark, or a function signal. The significance intended is indicated by a key code signal which causes the telegraph printer to shift to upper case, if it is the figure shift" signal, or to shift to lower case, if it is the letter shift" signal. Since the printer remains in either case position until shifted by the opposite case shift signal, it is only necessary to insert a key code signal when there is a change in the class of characters. The insertion of the key code signal is done automatically by the control apparatus, as described in application Serial No. 450,248. 1

Operation To illustrate one till of work where the in-- vention comes into use, assume a branch ofiice reporting to the main office upon the issuance of various stock items of four different classes. The information is stored on detail cards, such as shown in Fig. 5. At the left end of this card are two fields denoted by vertical lines, occupying columns 1 to 15, to receive the name and From columns 16 to 41 there are four fields reserved for the four classes of stock, respectively. The card will have in one of these four fields the stock item number. In Fig. 5 the stock item number appears in the field denoted Class 3. Beginning at column 4-2 is a field entitled Issue, wherein the number of items issued in the transaction noted in this card is punched. After this there are two fields for the month and year. The card contains two additional fields for data showing the stock remaining on hand and the number of Y the stated items issued during the year to the date given on the card.

It will be observed that the fields for classes 1, 2 and 4 contain a single hole in the X position in the first column of each field. These are X skip holes and indicate that the field is to be skipped over, without sensing the individual columns. This is the well known operation previously mentioned, whereby, in combination with a suitably notched skip bar the card is fed at once across the width of the field and then stopped. In the field reserved for the number of the month there is also shown a hole in the X position. This hole designates the eleventh month, i. e. November. It does not cause a skip feed of the card because the above mentioned notched bar has a deep notch opposite this column. This is all standard card operation. The diificulty which the present invention is designed to overcome occurs when a telegraph printer is operated under control of the card, or a tape prepared therefrom. The printer does not have a notched bar to determine whether the X hole in a certain column represents an X skip or an eleven.

In accordance with the present invention,

' means are provided to set up a different telegraphic code signal for these two significances of an X hole in the card. This is accomplished by means of a master card, such as shown in Fig. 4.

This card has an X hole in each column. corresponding to a column of the detail cardl where an X hole would represent an x skip operation.

- tion Serial No. 450,248). the detail card shown in Fig. is on the bottom In a column corresponding to one in the detail card where an X hole would represent 11, there is no X hole in the master card. The manner in which the master card effects its control will be seen from the following detailed description of the perforation of a tape under control of the master and detail cards shown in Figs; 4 and 5.

In preparing the apparatus to perforate, in a telegraph control tape, the statistical data contained in a stack of detail cards, the stack of cards is placed in a hopper to the right of the position of the detail card DC in Fig. 1 (see hopper ill in Fig. 1 of Mills 84 Rabenda applica- It will be assumed that of the stack. The master card shown in Fig. 4 will be inserted between the brushes lfll and contact roller 95 and between the fingers 91 and 98. A blank tape 200 (Fig. 2) is drawn out from a supply roll (not shown) and over the feed roller 26L The bottom card of the stack is manually fed to the position shown in Fig. 1, where its feed is taken over by the fingers l3 and I4. In passing to this position it closes the card lever contacts I56 (Fig. 3a) from the positive side of the line a circuit is thereby completed through the line switch (assumed to be closed), wire 360, latch contacts 35, wire 362, said card lever contacts I56, coil of relay RM to the negative line wire 36l, energizing said relay. Contacts Rllb close, completing a holding circuit for relay RH. Contacts Rl'la close, completing an obvious circuit through brush magnets 92 and I04, energizing said magnets and causing the brushes l2 and llll to be raised into contact with the cards DC and MC, respectively. Reading brush magnet contacts 95 open as the brushes are raised, deenergizing the coil of relay R, the function of which will be described later.

It will be assumed that the card reading machine is provided with a skip bar 50 (Fig. 1) having a high surface 50a coextensive with columns 1 to 15. This high surface of the skip bar lifts the escapement dog 41 from the rack bar' I5 and allows the latter to feed until the skip lifter 5| drops into the first notch 50c placed at column 16 and the dog 41 is therefore dropped onto the escapement bar to stop the latter in this column position. The floating cam contacts I49 are held open whenever the dog 41 is lifted from the-rack bar. As soon as the dog drops into the escapement bar, the floating cam contacts close and, since the brushes l2 and llll are at this time sensing column 16 of the detail card and the master card, respectively, circuits are completed from wire 360, through latch contacts 35, floating cam contacts I49, roller 9|, the hole in the card DC in the X position and the related brush [2, relays RX and RI I, to ,wire 36l; also, through contact roller I05, the X hole in the card MC,brush llll in the X position, relay RN to wire 36!. Relays RX, RI I, and RH are energized, but the operation of their contacts is not immediately effective and reference to them will be deferred for the present.

The operator now presses the start ke (Fig. 3b) closing contacts 350 andcompleting an obvious circuit from wire 360, through said contacts and relay R20 to wire 36l, energizing said relay. Contacts R20b close completing a holding circuit for relay R20 from line wire.360, through tape controlled contacts 3ll (which are closed as long as the tape is present in the punch), the contacts 35f of the start key, said contacts R2llb, and relay R20 to line wire 36!. Contacts R201;

close to prepare a circuit which will be referred to later on. Contacts R200 also close, completing a circuit from wire 360, through latch contacts 35, floating cam contacts 149, wires 363, 364, contacts Rl4c (now closed), said contacts R200 and relay RM to line wire 36l, energizing said relay. The relay R2l is one of a chain of timing relays. Its contacts R2Ia close to complete an obvious circuit through the latch contacts and wire 362 to relay R22 and R24, energizing said relays. The contacts R22a close to complete a circuit through relay R23,- energizing said relay.

The timing and function of these relays RH.- R24 are explained in the Mills and Rabenda application Serial No. 450,248 and Rabenda application Serial No. 510,156. Briefly, the relays R2 |--R23 provide a delay between the sensing of a column of the control records and the energizationof the distributing relay (Fig. 30) which is to select the tape punch magnets corresponding to the translation of the code combination sensed. This delay provides time for a supervisory mechanism to be operated if there is a change in the class of character, to delay the energization of said distributing relay until the next cycle, to disable the escapement control for one cycle, and to cause an appropriate key code signal to be punched in the tape. A key code signal is always punched when the sensing mechanism first becomes effective on a new card, or upon sensing the first column following an X skip. The relay R24 has the function of maintaining the punch shaft in continuous rotation, except under certain conditions to be explained.

Immediately upon energization of relay R2l, contacts R2511. close, completing a circuit from wire 360, through normally closed contacts Cl, wire 365, stop contacts R2541, the holding coil of relay R25 to line wire 36!. Contacts R2lb close, extending a circuit from wire 364, through said contacts, contacts R400 (normally closed), contacts Rlflb in normal position, contacts Rl la. in transferred position, (relay RH was energized), contacts Rl3a and R3011 in normal position, the pickup coil of relay R25 to line wire 36 l, energizing said supervisory relay. Contacts R250 open, disabling the circuits to be described presently to the distributing relays (Fig. 3c) and to the' escape magnet 40 (Fig. 3a). Thus, when contacts R23a close later, said circuits will be open at the contacts R250. Contacts R252 close to prepare a. circuit which will be referred to presently, while contacts R2512 open to disable a circuit referred to later on. Contacts R251) (Fig. 3e) close, completing a circuit from wire 36!), through normally closed contacts Cl, wire 366, said contacts R25b, wires 3', 312, 314 and 315, and tape punch selector magnets 232 pertaining to the tape code positions 1, 2, 4 and 5, to wire 36I, energizing said selector magnets. The contacts 3 (Fig. 2) are closed by the bail lever 3I5, completing a circuit from wire 36!], through normally closed contacts Cl, said contacts 3| I, tape punch clutch magnet 300, relay R29 to wire 36!, energizing said magnet and said relay.

Contacts R19b close to prepare a circuit branch shunting the bail lever contacts 31 1.

The branch circuit provides for continuous operation of the punch shaft in the manner described in the Mills and Rabenda application Serial No. 450,248. A circuit is also extended from line wire 360, through contacts C1 and C2 and through contacts R25e (now closed). pickup coil of relay R30 to wire 36 I, energizing said relay. Contacts R30b close, completing a circuit through the holding coil of relay R30 extended from wire 362, through contacts R26d (normally closed), said contacts R301) and said holding coil to wire 361. Contacts R30a open, disabling the circuit through the pickup coil of relay R25. When contacts C1 open soon after the punch shaft begins to rotate, the circuit through the holding coil of relay R25 is broken and said relay becomes deenergized. It cannot be energized again so long as contacts R3011 remain open. The opening of contacts C1 also deenergizes the tape punch clutch magnet 300, but this magnet is reenergized when these contacts close before the end of the revolution of the punch shaft, because of the circuit extending through contacts R191) and R24a, so that a second revolution follows immediately. The opening of contacts C1 and C2 deenergizes the pickup coil of relay R30 and the contacts R25e maintain the circuit to this coil open. The opening of contacts C1 and R25b also breaks the circuits to the tape punch selector magnets 232.

When contacts C1 close near the end of the first revolution of the punch shaft, a circuit is extended from wire 360, through contacts R2311, R250, R260, and R21c (all now closed), wire 369, contacts BM in normal position, contacts RXc in transferred position, contacts Rlb, R2bR1b, R80, R90 (all in normal position), wire 391, contacts R11a in transferred position, wire 400, the pickup coil of relay R40, to wire 361, energizing said relay. Contacts R40a and R40b close, extending a circuit from wire 366, through said contacts R40a and the holding coil of relay R to wire 361, and from wire 366 through said contacts R401) and wires 311, 314 and 315 through the tape'punch magnets 232 for code positions 2, 4 and 5, to wire 361, energizing said magnets. On the second revolutionof the punch shaft, the combination 2, 4, 5.is punched in the tape (see Fig. 6), designating a skip or tabulate function. Contacts R400 open, disabling the circuits of the supervisory relays R25 and R26. Contacts R40d open, breaking the holding circuit of relay R30. Contacts R3011 close, restoring the supervisory circuits to normal condition. 1

On closure of contacts C1 before the second cycle begins, a circuit is also extended through wire 368, escape magnet 40 and the pickup coil of relay R16 to wire 361. The energization of relay R16 at this time has no significance. Also. the energization of the escape magnet 40 at this time is of no consequence, because the control is taken over by the skip magnet, as will now be explained. On closure of contacts C1 at this time acircuit is also extended from wire 391, through contacts RXa (Fig. 3b) and pickup coil of relay R21, to wire 361, energizing said relay. Contacts R210 close, completing a circuit through the holding coil of relay R21, through the contacts CI. The contacts R21b open, breaking the holding circuit of-relay R19. Contacts Risa and R19b open, the latter breaking the shunt circuit around the bail contacts 31 I. The punch clutch magnet 300 will, therefore, remain deenergized and the clutch will latch up at the end of the cycle. Contacts R21a close (Fig. 3a), completing a circuit from wire 360, through'latch contacts 35, wire 362, said contacts R21a, pickup coil of relay R15, skip magnet 56 to line wire 361, energizing said pickup coil and said magnet. Contacts R1-5a close, preparing a holding circuit for relay R15, to be described presently. The skip magnet 56 shifts the skip lifter 51, which rises on the skip bar 50, raises the dog 11, and holds it out of engagement with the escapement bar 15 until the latter has traveled to column 22 position, where the next notch of the skip bar occurs. The lifting of the dog 41 opens the floating cam contacts 149. One efiect of this is to deenergize the relay R63, so that the contacts R6311 close and complete the holding circuit for relay'R15 from wire 360, through latch contacts 35, wire 362, said contacts R63a, contacts R15a, and skip magnet 56, to wire 361.

The opening of the floating cam contacts 145 breaks a number of other circuits, including those through relays R11, RX, R11 and R21. Contacts R21a open, deenergizing relays R22 and R24, and contacts R22a open, deenergizing relay R23.

On reaching column 22 position, the dog 41.

drops upon the escapement bar-and stops the card feed, also allowing floating cam contacts 149 to close. Relay R63 is thereby reenergized and opens thecontacts R6311, deenergizing the relay R15 and the skip magnet 56. The brushes 12 and 101 are at this time sensing column 22 of the detail card and the master card. Since the circuits are now in exactly the same condition as when the cards entered column 16 positiomand since the perforations in column 22 of the master and detail cars are identical with those in column 16, the machine will go through exactly the same sequence of operations, punching the flgures shift code and the "TAB code in the tape and skipping to column 28.

When the floating cam contacts 149 close, upon arrival of the cards in the column 28 position, circuits are completed through said contacts, the contact roller 91, the hole in the 0 position of the detailcard and the related brush 12, relays R0 and R12, 6 to wire 361; also from contact roller 105, through the hole in the X position in the master card and the related brush 101 and relay R11 to wire 361. The relays R0, R12 and R11 are thereby energized; however, the energization of relay R11 at this time has no significance because there is no X hole in the corresponding column of the detail card. Also, upon closure of the floating cam contacts 149 a circuit is completed through wire 363, 364, contacts R140, R200 (now closed), and rela R21 to wire 361. The pickup of the chain of relays R21lR24 is thereby started. Also, closure of contacts R21b completes a circuit from wire 364,, through said contacts, contacts R400, R101) in normal position, R12b in transferred position, R1 111 in normal position, R1311 in normal position, R3011 (now closed), and the pickup coil of relay R25 to wire 361, energizing said relay. The figures shift code is perforated in the tape as before, while the card feed mechanism is held in the same position for one cycle. When contacts C2 close, soon after the punch shaft begins to rotate, relay R19 is picked up and closes its holding cir- R43 to wire 36i, energizing said relay. Contacts R39a and R4911 close, the former establishing a.

holding circuit for the relay R49 and the latter completing a circuit from wire 366, through said contacts to wires 312, 313, and 315 and punch selector magnets 232 for the 2, 3 and 5 positions, to wire 3'8i. The punch thereupon operates to perforate the tape with 2, 3, 5 combination representing a 0.

The other operations during which the columns 29 to 48 are sensed will not be described, since they are similar to those already referred to. When the cards arrive in column 49 position, there is a hole in. the X position of the detail card and no hole in the master card. The relay RX is energized as before, but this time the circuit completed by its contacts extends from wire 333, through contacts RRa in normal position, wire 313, contacts Rxc in transferred position, contacts Rib, R2b R11), R30, Ric (all in normal position), wire 39i, contacts R1 is in normal position, pickup coil of relay R43 to wire 3", energizing said relay. The contacts Rub extend circuits to wires 313, 333, 313 and through punch selector magnets 232 for positions 3, 4, 5 to wire 3", energizing said magnets. The tape punch is thereby caused to punch the combination 3, 4, 5 in the tape, representing a period. By convention a period, when appearing in a certain column, is interpreted as 11. In this case it means the eleventh month, i. e. November.

The sensing of the successive columns of the cards continues and the tape is perforated with the telegraphic code combinations shown in Fig. 6 in any column where a character code combination is sensed. In the particular illustration of the detail card shown on Fig. 5, columns 59-62 and 71-80 are skipped over by means of the high bar skip previously described, so that no code combinations appear in the tape corresponding to these columns.

As the card feed mechanism passes from the 79th to the 80th column position, the last column contacts I are closed, completing several cir-' cuits now to be described. It will be assumed that the switch SW2 is in the closed position shown in Fig. 3a. A circuit is completed from wire 333, through said contacts i, switch SW2, eject magnet I3 to wire 3" energizing said magnet and causing the detail card to be flipped into the eject hopper in the well known manner. A second circuit extends through the holding coil of relay RIB to wire 3", energizing said relay.

The contacts Ri3a close, extending the circuit through wire 3", contacts B23!) in normal position, contacts R2311 (now closed), contacts R23a and R321: in normal position, relay Rli to wire 3". Contacts Rlla and Rtib close, the first completing a holding circuit for the carriage return relay ROI and the second extending a circuit from wire 3", through wire 3" and punch selector magnet 232 for the 4 position, to wire 3", energizing said punch selector magnet and causing the punch to perforate the tape with the carriage return signal. Contacts Rtie' open, disabling the circuit to relay R32 temporarily. Contacts Ri'ic close, preparing a circuit which is completed upon closure of contacts C2 during the cycle in which the carriage return signal is punched and which runs from wire 38.0. through contacts Cl and C2, contacts R6 lo and the pickup coil of relay R32 to wire 38I energizing said relay. Contacts R32a close, completing a holding circuit for said relay from wire 330; contacts R32b open, breaking the pickup circuit of relay RSI.

Contacts R320 and Riie close. When contacts Ci open in the cycle during which the carriage returnv signal is punched in the tape, the relay R23, which is energized whenever the contacts Ci are closed, is deenergized. Contact R23a close, completing a circuit from wire 360, through said contacts R2311, the contacts R32c (now closed), contacts RBie and B33!) in normal position, the pickup coil of relay R62 to line wire 38L The relay R82 is energized and closes its holding contacts Rii2a and the contacts R3217; the latter complate a circuit from wire 333, through wire 312, and punch magnet 232 for the 2 position, to wire 3". The punch perforates a hole in the 2 position, a line feed signal. The contacts R320 close and, when contacts C2 close during the cycle in which the line feed signal is punched, a circuit is completed from wire 3", through contacts Cl and C2, contacts R320, the pickup coil of relay R33 to wire "I, energizing said relay. The holding contacts R33a close while the contacts R33b open, breaking the circuit to the pickup coil of relay R32.

The contacts Rilb open when the relay an is energized, as above described, breaking the holding circuit of relay Ril. Contacts Rila close, preparing a circuit for the motor 2". in the course of the operation initiated by the eject magnet I3, the auto start contacts 34 are closed, completing an obvious circuit through the trip magnet 32. This magnet causes the latch contacts 35 to open and contacts 33 to close, the latter completing the circuit through the motor 2". The function of the motor 23! is to feed a new card from the stack to the card sensing mechanism. This operation will not be described, since it has been'explained previously in Patent 2,315,- 741- and the Mills 8: Rabenda application Serial No. 450,248.

The tape shown in Fig. 6, when used to control an ordinary telegraph printer, will cause the latter to produce a printed record as shown in Fig. 7. At the upper left corner of this sheet the name and number of the depot have been typed in by the operator at the receiving station because, in accordance with the example, this information on the detail card is not perforated in the tape. The record sheet is ruled with vertical lines to separate the different fields in approximately the same way as the detail card. The first two fields pertaining to classes 1 and 2 are bhnk, as a result of tabulation control of the carriage of the printer resulting from the first four combinations punched in the tape. The next field relating to class 3 has the item number 0016583. This is followed by another blank field skipped by tabulation. The next field contains the number of items issued. In the following field the printer types a period. This being in the month field, it is understood to represent the eleventh month. The next three fields contain, respectively, the number of the year, the number of the items on hand, and the number issued during the year up to the date given. After printing the final 6, the carriage of the printer is returned and the paper is fed for a line, by the carriage return and line feed signals of the tape.
